The mini at that price is overcharging you by about $200, an additional 8GB shouldn’t cost $200, nor should an additional 256GB. You can buy a whole 2TB M.2 for less
Fast M2 2TB drive.
Of course the Mac has a faster GPU, switching to Apple silicon was always going to improve GPU performance …
Besides, I don’t think it’s a fair comparison but that isn’t the point. The point is that people were claiming no one offered 512 GB storage or 16GB memory for anywhere near the price of the Mac mini… I disputed that claim.
I have said that I think the mini should start at $699 and offer more memory and storage rather than creating a pointless base model at a lower price
